Hi, I was doing some filesystem backups from one USB device to another one this weekend and kept running into the problem of the xhci controller shutting down after an hour or so of high volume traffic. I finally captured the problem in the kernel log as this would also take out my keyboard, making it hard to recover from :) The log is below for when the problem happens, and then the devices are disconnected from the bus (ignore the filesystem errors, those are expected when i/o is in flight and we disconnect a device. Any hint as to what the IO_PAGE_FAULT error messages are? I'll go back to 5.13.y now and see if I can reproduce it there or not, as my backups are not yet done... thanks, greg k-h [Aug 4 09:48] xhci_hcd 0000:47:00.1: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0032 address=0xfffffff00000 flags=0x0000] [ +0.000012] xhci_hcd 0000:47:00.1: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0032 address=0xfffffff00f80 flags=0x0000] [ +0.000006] xhci_hcd 0000:47:00.1: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0032 address=0xfffffff01000 flags=0x0000] [ +0.000006] xhci_hcd 0000:47:00.1: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0032 address=0xfffffff01f80 flags=0x0000] [ +0.000005] xhci_hcd 0000:47:00.1: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0032 address=0xfffffff02000 flags=0x0000] [ +0.000006] xhci_hcd 0000:47:00.1: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0032 address=0xfffffff02f80 flags=0x0000] [ +0.000006] xhci_hcd 0000:47:00.1: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0032 address=0xfffffff03000 flags=0x0000] [ +0.000005] xhci_hcd 0000:47:00.1: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0032 address=0xfffffff03f80 flags=0x0000] [ +0.000006] xhci_hcd 0000:47:00.1: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0032 address=0xfffffff04000 flags=0x0000] [Aug 4 09:49] sd 3:0:0:0: [sdc] tag#21 uas_eh_abort_handler 0 uas-tag 1 inflight: CMD IN [ +0.000011] sd 3:0:0:0: [sdc] tag#21 CDB: Read(16) 88 00 00 00 00 01 8a 44 08 b0 00 00 00 08 00 00 [ +5.106493] xhci_hcd 0000:47:00.1: xHCI host not responding to stop endpoint command.
